' LOOM.

SPECIFICATION forming part of Letters Patent No. 655,642, dated August 7, 1900.

Original application filed July 19, 1899, Serial No. 724,385. Divided and this application filed November 1,1899. Serial No. 735,444. (N model.)

To ctZZ whom it may concern:

Be it known that we, WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIC E. KIP, residing 5 at Montclair, Essexcounty, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to the class of looms Io provided with mechanism for supplying to the loom automatically filled Weft-carriers and which are provided with monitors or detectors which act when the weft or filling in the running Weft-carrier or shuttle is nearly or wholly exhausted to set in motion the weft or filling supplying mechanism.

In this application, which is a division of our pending application, Serial No. 724,385, filed July 19, 1899, we have shown electrical 2o controlling devices and mechanical means for operating the shuttle-box and shuttle-placer, which are the same as those illustrated in our said application Serial No. 724,385; but these are not specifically claimed herein.

2 5 This invention relates, specifically, to the magazine which contains the filled weft-carriers or shuttles and which delivers them to the placer one by one, as required.

' In the accompanying drawings, which illus- 0' trate an embodiment of the invention, Figure l is a side elevation of a part of a loom, illustrating the application of our invention thereto. This view shows the lay or batten in its advanced position, having beaten up the shot,

3 5 and shows the shuttle-box and placer in their normal positions. Fig. 2 is a view similar to Fig. 1, but showing the lay receding and the placer in operation to supplya full weft-can rier. Fig. 3 is a view of the magazine in full,

40 it being partly broken away in Figs. 1 and 2- for lack of room. Fig. 4 is a side elevation of the fixed side of the shuttle-box, showing the electric terminals and circuit. Fig. 5 is a longitudinalsection of the shuttle and bob- 5 bin with their electrical devices.

Before minutely describing the construction of our weft-supplying mechanism it will be of advantage to point out the general character of the same. The magazine is staor arm, to which motion is imparted by a cam on the loom, so that this cam, through said. lever and suitable intermediate mechanism, shifts the displaceable shuttle-box, discharges the exhausted shuttle therefrom, puts the placer in position, and holds it in line with the picker until the full shuttle therein is picked to the opposite sideof the loom. The cam then passes and the parts resume their usual or normal positions until the shuttle in play is practically exhausted of weft, when 76 the supplying operation is repeated.

1 represents generally the frame of the loom; 2, the breast-beam thereof; 3, the lay or lay-head, carried by the lay-swords 3 which latter are fixed below to the swing-rail 7 5 4. The lay is vibrated in the usual manner, from a crank 5 and connecting-rod 5 All of these parts are common in some form on looms now in use, as are also the pickersticks 6. 80

The features which embody the present invention will now be described.

On the loom-frame is mounted a shuttlemagazine 7, which discharges at the bottom. At the delivery-outlet of the magazine is situated the. placing-pocket or placer 8, into which a shuttle S from the magazine is free to fall by gravity. The placer is a sort of trough mounted on an upright arm 8, which turns at its lower end on the swing-rail 4.- or 0 on some adjacent pivotal axis. A spring 9 of any suitable kind holds the placer in its normal receiving position. On the lay 3 is mounted the shuttle-box 10. This box consists of a stationary part and a movable part. The side 10 farthest from the magazine is fixed on the loom. The bottom 10 and the side next the magazine, including the swell When an exhausted shuttle enters 55 form a movable part, which is secured to a pair of stems 11, that are guided in suit able keepers 12 on the lay-head.- Connected to the stems 11 is 'an upright guide rod or slide 13, by which the box 10 may be raised and lowered to the proper extent.

The operating mechanism of the placer and shuttle-box will now be described.

On the frame of the loom a lever 14 is fulcr-umed at as, and one arm of this lever is coupled by a rod to one arm of an elbowlever 16, fulcrumed at its elbow on the upright slide 13. The other arm of the elbowlever is provided with a hook 16 ,which is adapted under certain conditions (to be hereinafter explained) to engage a stud 8 on the arm carrying the placer 8. On the other arm of the lever 14 is fixed an electromagnet M,

, the armature a of which is fixed on one arm of an elbow-lever 17, which is provided on its other arm with a hook 17. An ordinary armature-spring 17 holds the armature retracted normally, and a spring 14 holds the lever 14 in the normal position seen in Fig. 1. The crank-wheel 5 gears with a wheel 18 of twice its own diameter, and on the shaft 18 of said wheel is a cam 19, which will of course rotate once while the lay is making two vibratory movements. This cam 10 bears on an arm' or lever 20, which may be held up to the cam by a spring 21. This operating arm or lever is vibrated constantly while the loom is in operation, and it bears at its free end a book 20", which plays close to the hook on the armature-lever 17, and when the magnet M is excited and attracts its armature the lever 17 is rocked audits hooked end 17 a put into the path of the hook 20 Let us suppose that while the lay is at the picking-point an exhausted shuttle enters the shuttle-box 10 from the opposite side of the loom and through electrical means, to be hereinafter described, completes a circuit through the magnet M. The lay will afterward beat up the shot and start to recede; but before it again reaches the picking-point the cam 19 will depress the lever 20, which will engage the lever 14 and rock it, thus acting through the rod 15 and elbow-lever 16 to elevate the shuttle-box 10 and shift the placer 8 to the position seen in Fig. 2. The exhausted shuttle will be thrown from the open rear side of the shuttle-box and may be caught in a tray or receptacle 22 on the loom-frame. The full shuttle in the placer 8 will be picked to the opposite side of the loom. The cam 19 now passes, the placer is returned by its spring to its normal receiving position, and the shuttle-box descends to its normal position on the lay. As soon as the shuttle-box is elevated the circuit is broken, and the continued engagement of the lever 20 with the armaturelever 17 will be purelymechanical.

It should be explained that the picker and picker-stick are omitted from Figs. 1 and 2 to avoid obscuring the other parts. The

- metal ring or piece 30 on the bobbin.

picker-stick plays in a slot in the lay-head and in the bottom of the shuttle-box and also of the placer when the latter is on the lay, as seen in Fig. 2.

Fig. 3 shows the magazine 7, which forms the important feature of this invention. In this magazine, 7 is a fixed casing of drumlike contour, having at its under side apocket 7', open at the bottom to deliver a shuttle to the placer 8. Within the casing 7 is a rotatively-mounted drum 7, having at its periphery cells to contain the shuttles. At its top the casing is open, so that the shuttle-cells in the drum can be conveniently filled.' The shuttle in the lowermost cell of the drum passes down through the pocket, guide, or chute 7 into the placer. When the placer recedes from the picking position, Fig. 2, to the receiving position, Fig 1, a latch 26, carried thereby, engages one of a series of studs .27 on the end of the drum 7, thus turning it on its axis to an extent sufficient to bring the next shuttle-cell over the placer. When the placer advances, the latch 26 wipes under the stud 27, which it finds in its path. A spring-detent 28 by engaging the studs 27 steadies the drum in its set position.

The electrical devices employed in the shuttle-box, shuttle, and weft-carrier may be like any one of those shown in our several pending applications illustrating electricallycontrolled weft-supplying mechanism-for example, Serial No. 724,385, of which this is a division. As shown in Figs. 4 and 5, they consist of the instrumentalities which will now be described.

On the side 10 of the shuttle-box are mounted two spring-terminals t and t. These form terminals of an electric circuit comprising the conductors c c, the magnet M, and a suitable generator. G. On the side of the shuttle are two contact-plates p and p, which when the shuttle enters the shuttlebox are put into electrical contact with the respective spring-terminals t and t. The shuttle has hinged in it a bobbin-spindle 24,

TIO

on which is loosely mounted a metal ring 25,

which is electrically connected by a conductor 26 (through a spring 27 behind the ring) with the plate 19. The bobbin 28, which slips on the spindle 24 and carries the weft, carries a spring-terminal 29, which has electrical contact with the ring 28 when the bobbin is in place, and this spring-terminal tends by its resiliency to spring outward until its free end is in contact with the inner face of a This latter ring is connected electrically by a conductor 31 with a grooved metal ring or piece 32 on the bobbin, and when the bobbin is pressed down in the shuttle the said groove engages a metal rod 33 in the shuttle, which is in turn connected by a conductor 34 with the plate 19. The terminal 29 occupies a slot in the bobbin, and when overwrapped by the weft-thread its free end is held out of conhaving a rotary drum, with shuttle-pocketsand a delivery-chute at its bottom, a guided, shuttle-carrying placer which normally occupies a position under said chute to receive the shuttles, and a guided shuttle-box on thelay, adapted to be moved up and down, of means for simultaneously moving said shuttle-box upward and for moving said placer into the position left vacant by said shuttle-box, substantially as set forth.

2. The combination with the displaceable shuttle-box, the vibratable placer, and mechanism for operating said shuttle box and placer, of the magazine, comprising a stationary casing, having a delivery-chute at its lower part, the rotatable drum in said casing provided with cells or pockets for the shuttles and with studs at its end, of means carried by the placer for imparting intermittent rotative impulses to said drum, substantially as set forth.

3. Inaweft-supplying mechanism,the combination with a stationary shuttle-magazine having a rotary drum, with shuttle-pockets and a delivery-chute at its bottom, a guided, shuttle-carrying placer which normally occupies a position under said chute to receive the shuttles, and a guided shuttle-box on the lay, adapted to be moved up and down, of means for simultaneously moving said shuttle-box upward and for moving said placer into the position left vacant by said shuttleboX, and electromagnetic means for controlling the times of the operation thereof, substantially as set forth.

4. The combination with the displaceable shuttle-box, the vibratable placer, mechanism for operating said shuttle-box and placer, and electromagnetic means for controlling the times of operation of said mechanism, of the magazine, comprising a stationary casin g, having a delivery-chute at its lower part, the rotatable drum in said casing provided with cells or pockets for the shuttles and with studs at its end, of means carried by the placer for imparting intermittent rotative impulses to said drum, substantially as and for the purposes set forth.

In witness whereof we have hereunto signed our names, this 30th day of October, 1899, in the presence of'two subscribing witnesses.
